2 Claims. (crate-"1 1 "This invention relates to new and ii's'e fii limmine car'sand the vide an attachment for a mine car that will scaleloose rock from a mine roof as the mine car is moving.

Another object of the present invention is to provide a mine roofscaling attachment ior mine cars that will eliminate the necessity ofhaving to employ operators using pick andslate bars.

Yet, another object of the present invention is the provision of a mineroof sealer that will permit slate and bone to be removed from the roofof a mine in a safe and convenient manner without having to employexplosives.

Another very important object of the present invention is to provide amine car attachment that will permit loose rock on the roof of a mine tobe scaled without the risk of placing operators beneath a weakened roof.

A further object of the present invention is to provide a mine roofscaler that is mounted on one car and disposed over a'second car so thatas the cars move forwardly slate or bone removed by the sealer will fallinto the second car thereby eliminating the necessity of having diggersor workmen for loading mine cars with scale or bone.

A still further aim of the present invention is to provide a mine roofsealer that is simple and practical in construction, strong and reliablein use, small and compact in structure, relatively inexpensive tomanufacture, that is quickly and readily applied to or removed from amine car, and otherwise well adapted for the purposes for which the sameis intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view of the present invention applied toa mine car and showing the present invention in use for sealing a mineroof;

Figure 2 is a perspective view of the present invention applied to amine car (shown in part) and Figure 3 is a fragmentary longitudinalvertical sectional view of the present holder and showing the blade, inelevation, applied thereto.

Referring now to the drawings in details, wherein for the purpose ofillustration, there is disclosed a preferred embodiment of the presentinvention, the numeral 10 represents a base member generally, includinga substantially rectangularLpIa'te 12 and a .pair of spaced walls orsup- ;ports 14 that are fixed to and which rise from the plate 12.

An elongated holder or tubular member i6 .is associated with the basemember ID and includes first and second end portions l8 and 20. The endportion I8 is transversely apertured, as at 22, and registers withsuitable apertures provided in the walls l4. The aperture 22 and theapertures in the walls 14 in registry with the aperture 22 receive abolt and nut 24 for pivotally securing the holder Hi to the walls l4.

The end portion 20 receives the shank portion 25 of an arcuate blade orscraper 28 and the shank portion 26 is apertured, as at 30, to registerwith suitable openings in diametrically opposite sides of the endportion 20.

A plurality of vertically spaced openings 32 are provided in each of thewalls l4 and are disposed on an arc to selectively register with theaperture 30 in a shank portion 26 and the openings in the end portion 20in registry with the aperture 30. A bolt 34 extends through the aperture3|] and the openings in the end portion 20 in registry with the aperture30, as well as selected openings 32 in the walls [4 to retain the holderl6 and blade 28 in a selected vertically inclined position. The bolt 34is provided with a complemental nut to retain the same in position tothe holder, blade and walls 14.

Suitably fixed to the upper wall 36 of a mine car 38, is a pair ofspaced parallel angle iron members 40 that slidably receive the sideedges of the plate l2. The plate I2 is held fixed to the angle ironmembers 40 by any suitable number of screws 42 that are threaded to theangle iron members and which are receivably engaged in threaded openingsin the plate l2 and, if desired for additional strength, openings in thewall 35.

In practical use of the present invention, the base member I0 is mountedon the car 38 and the blade 28 is disposed over a further car 44 that iscoupled to the car 38. The car 38 is provided with a suitable motor formoving or pushing the cars 38 and 44 forwardly, the car 38 trailing thecar 44.

As the cars move, the blade 28 will scrape or scale the bone or material46 from the roof of a mine or tunnel, and the material 46 will fall intothe car 44.

By adjusting the angular position of the holder 16 and blade 28, apredetermined amount of the material 46 can be removed from the mineroof.

In view of the foregoing description taken in conjunction with theaccompanying drawings it 3 is believed that a clear understanding of thedevice will be quite apparent to those skilled in this art. A moredetailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain changes fully comprehended by the spirit of theinvention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A mine roof scaler comprising a base member including a pair ofupstanding walls,: a tubular holder pivoted at one end between thewalls.

said holder having a transverse opening in its opposite end, said wallshaving a plurality ofopenings therein for selectively registering withthe opening in said holder, a holding bolt received in the openinginlsaid holder and selected 20 openings in said walls for retaining.theholder in a selected pivoted position, and a bladehaving an endretained in said holder by said holding bolt. a

2. In a vehicle for mines including first and second cars coupledtogether; the improvement of which comprises a base mounted on thesecond car and including a pair of spaced walls, a tubular holderpivoted at one end between said walls, a blade carried by said holderand disposed over the first car for scaling a mine roof and permittingthe scaled material to fall into the first car as the cars are movedwith the first car leading me second'car, and means for retaining theholder in aselected pivoted position.
